U1: Introduction to Probability Summative Assessment Georgia Tselikis Reid 05/20/21 1. Georgia has 15 apps on her phone. Of these apps, 10 are connected to social media, 7 are games, and 5 are games that are connected to social media. Total # of Apps on Georgia’s phone: N = 15 The # of apps connected to social media: n (S) = 10 The # of games: n(G) = 7 The # of games connected to social media: n ( S G ) = 5 a. Are the apps mutually exclusive or non-mutually exclusive? Justify your answer.
b. Find the probability that a random app on Georgia’s phone is not connected to social media and is not a game. Insert screen capture from the Venn Diagram interactive or draw the Venn Diagram by hand and take a picture. G ) = 5/15 = 0.333
OR Perhaps, assuming that these 15 apps are the only apps on Georgia’s phone, then the probability that a random one is neither a game or social media is zero because it is stated that all of the apps either consist of social media, games or both. 2. Write and solve a probability question associated with this scenario. Explain your steps in the solution and use correct notation. Include in your submission a tree diagram and use of the fundamental counting principle. Are the events independent or dependent? Justify. The caterpillar has 3 paths, straight, left or right. What is the probability that the caterpillar hits the box on the right?
